The warning/alarm information below defines each
warning/alarm condition, provides the probable cause for
the condition, and details a remedy or troubleshooting
procedure.
WARNING 1, 10 Volts low
The control card voltage is below 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA or minimum 590
Ω
.
This condition can be caused by a short in a connected
potentiometer or improper wiring of the potentiometer.
Troubleshooting
Remove the wiring from terminal 50. If the warning clears,
the problem is with the customer wiring. If the warning
does not clear, replace the control card.
WARNING/ALARM 2, Live zero error
This warning or alarm only appears if programmed by the
user in
AN-01 Live Zero Timeout Function . The signal on one
of the analog inputs is less than 50% of the minimum
value programmed for that input. Broken wiring or faulty
device sending the signal can cause this condition.
Troubleshooting
Check connections on all the analog input
terminals. Control card terminals 53 and 54 for
signals, terminal 55 common. OPCGPIO terminals
11 and 12 for signals, terminal 10 common.
OPCAIO terminals 1, 3, 5 for signals, terminals 2,
4, 6 common).
Check that the adjustable frequency drive
programming and switch settings match the
analog signal type.
Perform Input Terminal Signal Test.
WARNING/ALARM 4, Mains phase loss
A phase is missing on the supply side, or the line voltage
imbalance is too high. This message also appears for a
fault in the input rectifier on the adjustable frequency
drive. Options are programmed at
SP-12 Function at Line
Imbalance .
Troubleshooting
Check the supply voltage and supply currents to the
adjustable frequency drive.
WARNING 5, DC link voltage high
The intermediate circuit voltage (DC) is higher than the
high voltage warning limit. The limit is dependent on the
adjustable frequency drive voltage rating. The unit is still
active.
WARNING 6, DC link voltage low
The intermediate circuit voltage (DC) is lower than the low
voltage warning limit. The limit is dependent on the
adjustable frequency drive voltage rating. The unit is still
active.
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit, the
adjustable frequency drive trips after a time.
Troubleshooting
Connect a brake resistor
Extend the ramp time
Change the ramp type
Activate the functions in B-10 Brake Function
Increase SP-26 Trip Delay at Drive Fault
If the alarm/warning occurs during a power sag,
the solution is to use kinetic backup (
SP-10 Line
failure )
